This Quick Installation Guide explains how to install the LSI
Logic MegaRAID LSIiBBU01 Intelligent Battery Backup Unit
on a MegaRAID SATA 300 PCI-X to Serial ATA storage
adapter. The LSIiBBU01 protects the cached data on the
MegaRAID storage adapter by providing backup power if the
main AC power source fails or is interrupted.
The LSIiBBU01 is compliant with the Smart Battery Data
Specification, which relieves the host system from the
responsibility of communicating battery information and
charging the battery.
You can view information about the LSIiBBU01, such as
battery temperature and voltage, in the BIOS Configuration
Utility and the WebBIOS Configuration Utility. Battery
charging and recharging takes place automatically.
The following sections describe how to install the LSIiBBU01
and list the basic hardware specifications for it.
Installing the LSIiBBU01 on the Storage
Adapter
Caution: Electrostatic discharge can damage the
LSIiBBU01 and the MegaRAID SATA 300 storage
adapter. Be sure to install the LSIiBBU01 at an
ESD-safe workstation that meets the
requirements of EIA-625 – “Requirements For
Handling Electrostatic Discharge Sensitive
Devices.” When you install the LSIiBBU01, follow
the ESD-recommended practices in the latest
revision of IPC-A-610.
If the MegaRAID SATA 300 storage adapter is already
installed in a computer, follow these steps to remove it before
you install the LSIiBBU01:
Step 1 Shut down the computer, turn off the power, and
unplug the power cord(s).
Step 2 Remove the cover from the computer according
to the instructions in the system user’s manual,
so you can access the PCI-X slots.
Step 3 Ground yourself before touching the MegaRAID
SATA 300 storage adapter.
Step 4 Unplug all cables from the MegaRAID SATA 300
storage adapter, remove the screw attaching the
bracket to the computer case, and carefully
remove the storage adapter from the slot.
Step 5 Place the storage adapter on a flat, clean, static-
free surface, and continue with the next section.
Follow these steps to install the LSIiBBU01 on the
MegaRAID SATA 300 storage adapter:
Step 1 Ground yourself, and remove the LSIiBBU01 from
its package.
Figure 1 shows top and bottom views of the
LSIiBBU01. Note the J2 and J14 connectors and
the holes for the screws that attach the
LSIiBBU01 to the MegaRAID SATA 300 storage
adapter.

Unit
Step 2 Insert the battery pack harness connector (at the
end of the colored wires) into the J2 connector on
the bottom side of the LSIiBBU01.
Step 3 Place the MegaRAID SATA 300 storage adapter
front-side-up on a flat, clean, static-free surface.
Step 4 Hold the LSIiBBU01 so that the battery side is up
and the J14 connector lines up with the J3
connector on the MegaRAID SATA 300 storage
adapter, as shown in Figure 2.

Step 5 Carefully press the LSIiBBU01 onto the storage
adapter, so the J3 and J14 connectors are firmly
joined.
Step 6 Using the three Philips-head screws that are
provided, secure the LSIiBBU01 to the storage
adapter, as shown in Figure 2.
Caution: Center the screwdriver carefully to avoid stripping
the screw heads. Do not over-tighten the screws.
The maximum recommended torque is 2.25 inch
pounds.
Step 7 Install the MegaRAID SATA 300 storage adapter
in a PCI-X slot in the computer, as shown in
Figure 3.
Press down gently, but firmly, to ensure that the
storage adapter is properly seated in the slot. The
bottom edge of the storage adapter must be flush
with the slot.
Caution: Never apply pressure to the LSIiBBU01 when
inserting the adapter. Instead, press down only
on the top edge of the storage adapter board, as
shown in Figure 3.
Step 8 Attach the storage adapter to the computer
chassis with the bracket screw.
